(Granted undei the act of March 3, 1883, as amended April 30, 1928; 370 O. G. 757) 2 Olaims.

The invention described herein may be manufactured and used by er for the Government for governmental purposes, without the payment 120 me cf any royalty thereon.

This invention relates to a 13001 for intiating the removal of a cartridge extractor from a rifie holt of the type shown in U. S. Patent 2,198,610.

The purpose of the invention is o provide a simple tool which may be conveniently applied to a rifie to initiate removal cf the extractor while the holt is in the gun so that the firing pin may be quickly removed a nd replaced.

The specific nature of the invention as well as other objects and advantages thereof will clearly appear from a description of a preferred embodiment as shown in the accompanying drawing in which:

Fig. 1 is a fragmentary view of a gun with the improved 13001 in position 130 remove the extractor;

Fig. 2 is a perspective view of the tool;

Fig. 3 is a view in side elevation of the head member of the tool, and,

Fig. 4 is a view in side elevation and partly in section of the guide member of the tool.

Referring to the drawing by characters of reference there is shown a portion of a semi-automatic rifle in which a breech holt 5 is reciprocally mounted in a receiver 6 and is adapted to be partially rotated into and out of locked in battery position. The extractor I is formed with a trunnion 8 Which is journaled transversely in the holt and extends through a slot or groove 9 in the firing pin I0 130 limit longitudinal movement of the firing pin as Well as to restrain lt against rotational displacement. Thefiring pin can only be removed from the holt when the trunnion of the extractor is disengaged therefrom.

The too1 for initiating removal of the extractof comprises a brass guide member and a stee1 head member. The guide member includes a cylindrical rod II which is adapted to enter the Cartridge chamber of the harre] when the breech holt has been retrated. A collar I2 011 the rear end of the guide merges With the rod through a tapered shoulder I3 which is adapted to engage in the shallow holt recess I4 in the barrel.

The steel head member is rotatably connected 120 the brass guide member in any suitable manner. A convenient connection consists in providing on the head member a stem I5 which is inserted in an axial recess I6 in the guide and which is formed with a peripheral groove I'I for receiving a pin I8 passing eccentrically through the collar I2. The head member includes a collar I9 which abuts the collar I2 and carries a handle 20 whereby the 12001 is readily manipulated and the head member rotated with respect to the guide member. A reduced cylindrical knob er button 21 is formed on the rear of the collar I9 and simulates the base of a cartridge case. The button is shaped for engagement by the front of the breech holt a.nd has one side cut away as a1: 22 to avoid interference With the extractor.

A pin 23 is fixed in the collar I9 and has a. reduced and shaped end 24 projecting rearwardly alongside of and beyond the button. The shaped end 24 of the pin is adapted to engage the under su1face of the (extractor I.

In employing the t001 the breech holt 5 is retracted sufiiciently to permit the 13001 to be placed in front of the holt and insert its rod II into the cartridge chamberof the barrel. The pin 24 bears such an angular relation to the handle 20 that lt Will be in proper position underneath the extractor When the handle 'is slightly the right of vertical. The breech holt is now eased forwardly into engagement with the tool and is thereby brought to rast a short distance out of battery. Upon rotating the handle 130 the left the pin 24 is angularly displaced and initiates withdrawal of the extractor from the breech holt. The extractor is now lifted out, the rifle is inclined and the firing pin, which is no longer restrained by I:he trunmon of the extractor, falls out. When the firing pin has been replaced, the extractor is reassembled 110 the holt and the tool removed.

I claim:

1. In a too1, a guide member adapted for chambering in a gun barrel, a head member rotatably engaging the guide member anal having a rear end adapted for engagement with a breech holt, a pin eccentrically carried by the head and projecting rearwardly for engagement with a removable element of the breech holt, and a handle on the head member having a Dredetermined angular relation to the pin.

2. In a tool, a guide member adapted. for Chambering in a gun barrel, a head member rotatably engaging the gui-de member and having a rear end adapted for engagement With a breech holt, a pin eccentrically carried by the head and projecting rearwardly for engagement with a removable element of the breech holt, and a handle on the head member.
